CAR-D UMPING APPARATUS.

Specification of `Letters Patent.

Patented Aug. 25,1914.

Application filed July 19, 1911. Serial No. 639,306.

y To all 'whom it may concern More specifically my invention relates to apparatus such as that disclosed in Patent No. 982,426 for mine car dumping apparatus, issued to Charles A. Griffith, Janu ary 28, 1911.

My invention has for its object to provide a dumping apparatus of this class having improved means for controlling the movement of a car.

Other objects will be apparent from the following specification.

In the accompanying drawings, which form a part of this specification, Inhave shown that form of mechanism which I now deem preferable. However, it will be ob vious that certain changes and modifications may be made within the spirit and scope of my invention.

Uf the drawings, Figure 1 is a side elevation. Fig. 2 is a plan view, Fig. 3 is a cross sectional elevation `taken along the line 3-3 of Fig. 1. Fig. 4 is a cross sectional elevation taken along,` the line 4 4 of Fin'. 1.

Referring to the drawings, 1 and 2 repre sent two substantially horizontal track sections positioned at different elevations. These track sections may be mounted upon any suitable frame work, such as that shown in the drawings. Between these two track sections there is located a connecting section comprising,` two rails 3, These rails are preferably rectangular in cross section and are narrower than the treads of the ordinary track rails. Each of the rails 3,3, is shaped to have one part 4 in substantial alinement with the upper main track sec- `10, 10, and are tion 1, another part 5 in substantial alinement with the `lower'niain track section 2,

and an intermediate sharply inclined part 6 between the parts 4 and 5.

`7 1s a transverse shaft rotatably mounted `in suitable bearings 8, 8 secured to the rails 3, 3, preferably on the inclined parts 6, 6.

9, 9 are horns rigidly secured to the shaft 7 at points adjacent and outside of the bearings 8, 8.` These horns are adapted to swing with the shaft 7 about the axis thereof into and out of the paths of the wheels of a car on the track. The horns 9, 9 are provided with counte1\veiglited rearward extensions preferably formed `of cast steel. In order to reduce the expense, the

counter-weighted ends of the horns may be provided with cast iron blocks 11. F or different installations the blocks 11, may be varied in thickness in order to adapt the `mechanism for the peculiar conditions.

Stops 12, 12 are provided on the inclined parts 6 of the rails, these stops being adapted to engage the horns to limit their upward movement@ It will be observed that the two horns are engaged simultaneously and that there is on this account no tendency for tor-` sional strains to be set` up inthe shaft 7. At one end of the shaft 7 there is provided a brake wheel 13 which is provided with a V-shaped circumferential groove. 14 is a brake band for the wheel 13. To this brake band are secured wearing' blocks 15 which are shaped to engage with the groove of the wheel and to be thus held in alinement therewith.

`16 is a rock shaft mounted in bearings suitably connected with the rails. The shaft extends parallel with the shaft 7. At one end of the shaft 1G is an operating lever 17 which is provided with a handle 18. Sccured to the shaft 16 in respective aline` ment with the horns 9, 9 are two stop dogs 19. When in the position shown in Fig. 1, the dogs 19 engage the ends ofthe horns 9, 9, and serve to prevent their movement in the direction of the arrow. It will be observed that the ends of theihorns are formed in the arc of a circle which, when the horns are in the position shown, is concentric with the axis 0f the rock shaft 16.

As a result 0f this construction the horns are held always in the same position irrespective of the exact position of the dogs.

The hand lever 17 is provided with a downward extension 20 to the lower end of which there is pivotally connected one end of a horizontal link 21. The other end of this link is pivotally connected with the lower end or" the lever 22 which is rigidly secured at its upper end upon a suitably mounted rock shaft 23. The rock shaft 23 also carries a lever 24 at the outer end of which are pivotally connected depending links 25.

26 is a lever which is pivoted intermediate its ends upon the shaft 16. One part 26'nl of the lever 26 consists of two forks which eX-v tend horizontally and which carry a shoe 27 adapted, when in proper position, to engage with the brake wheel 13. The other part 26b of the lever 26 also extends substantially horizontally but is offset into a plane below that of the part 26a. The outer end of the part 26h is pivotally connected with the lower ends of the links 25. Slidably mounted upon the part 26b is a weight 28 which may be secured in any one of a plurality of positions by means of a pin 29 which is adapted to extend through any one of the apertures 80. While I have described the parts 2Ga and 26b as comprising one single lever, it will be understood that for convenience of construction, these may be made as separate parts and bolted or otherwise secured together. lVhen completed, however, they constitute one rigid whole.

One end of the brake band 14 is secured in any desired manner to the main 'track supporting trame. The other end has secured to it a threaded rod 31 which extends throughan aperture in a yoke 32 which is pivotally mounted between'the two forks of the lever part 26a. The position of the rod 31 with respect to the yoke may be adjusted by means of the lock nuts 33 and 34.

35 indicates a car in dumping position. Any desired type of car adapted for the purpose may be used. The end door may be opened either by hand or by any desired mechanical means. In the drawings, l have indicated substantially horizontal bars 36 for engaging the door parts to hold them relatively elevated when the car is in dumping position. However, other means may be used, if preferred. 37 is a chute mounted beneath the rails 3, 3 for receiving the coal or other material as it slides from the car.

In operation let it be assumed that there is no car on the dump and that the horns are in the position marked a. Let it also be assumed that the lever 17 and the parts connected with it are in the position shown in the drawings, the brake band 14 being tensione-d by means of thev weight'28. As a loaded car approaches dumping position, its

forward wheels are engaged by the two horns 9, 9, and the car is gradually brought to rest because of the resistance oleied t0 the movement of the horns by the brake. The dogs 19 engage the rear ends of the horns 9, 9 and temporarily maintain them in the position designated by Z2 and shown by full lines in Fig. 1. The car is maintained in this position until. its contents have been discharged through the opened end. After the discharge of the contents ot' the car, the operator moves the lever 17 in the direction of the arrow suthciently to release the dogs 19 *from engagement with the rear ends of the horns. By means of the system of linkage which has been described, the lever 26 is at the same time moved sutliciently to release the brake band 14 and simultaneously apply the brake shoe 27. The lever system interposed between the hand lever 17and the lever 26, is a force increasing one and a relatively small force applied to the handle 18 is sutlicient to move the lever 26 and raise the relatively heavy weight` 28. VThe horns 9, 9, after being released by the doUs 19, are free to move under the weight of the car 35 inasmuch as the brake band 14e has been released simultaneously with the movement of the dogs. A relatively small braking edect is applied to the wheel 13 by means oi the shoe 27, but this is not sinlicient to materially retard the movement of the horns under the weight of the car from the position 5 to the position 0. However, the braking effect of he shoe 27 is sufficient to prevent the return of the horns by the action of gravity to the position tu Therefore, the horns may be held by the operator in the position o until the rear wheels of the car have passed. Vilere it not for the shoe 27, or its equivalent, the horns would return under the action of gravity and would engage with the rear wheels ofthe ear and possibly cause derailment. After the rear wheels of the car have passed the, horns, the operator releases his hold on the handle 1S and the weight 28 immediately causes the shoe 27 to be moved out of engagement with the wheel 153, the brake band 14 to be ensic-ned, and the lever 17 to be returned to its normal position. The operator, by retarding1 the return movement o the lever 17, will give the horns oppor tunity to return by gravity to position a after the release of the shoe 27, and before the application of the braking etl'ect on the band 1li. y

t will be observed that by my improved construction l have provided means whereby the movement of the car may be completely controlled by the operator with a minimum of effort by means of a single l ver. The brake is automatically applied by the weight 2S, but the normal braking etl'ect of the weight may be gradually inby the stop dog to arrest the movement of the device together with that ot the car, means for moving the stop dog out of engagement With the element and for simultaneously releasing the said brake whereby the device is permitted to move to its eX- treme position out ot the path of the car, automatic means ior returning the device to its initial extreme position, and manually controlled means tor retarding the said return movement.
